Jazzy, your method is what I had in mind, Aero's idea was a great idea but after tearing into the power supply I found that the wires were soldered on to the connectors. I was back to where I started trying to find a way to mount the PS plug. I would rather use the screw type terminals then soldering wires to the terminals.

I plan on building a box on the tongue of the trailer up against the main vertical wall of the closure that will house a 12 volt marine battery. there is where I will also house the the male end of the extension cord.

I have ruled out the male end to male end pig tail.

Some background of myself; The company I work for now is the City of Austin Electric "Austin Energy" 17 1/2 years with 5 1/2 more to go before retirement, when I first started with AE I was in substation maintenance "38kv and up" for 6 years and then migrated over to transformer shop where I did another 4 years, my next move was a career change into the world of computers where I now sit behind others computer helping them with their problems.

The idea of building the male to male pigtail was a foolish thought on my part and I of all should have known better. I have seen what the higher voltage can do to someone and have even gotten bit myself by 220 a few time's, OUCH!! I really! really! don't want to be taped by 220 anymore much less 120 for that matter.

As far as the inverter, I don't have one as of yet but do plan on purchasing one. I do have a 10amp power supply that converts AC to DC that I will be using as well.
